英文摘要	To control the shape and structure of a metal nanoparticle (NP) is a crucial strategy to improve its catalytic properties, but the understanding and quantitative description of the structure reconstruction of the catalysts under reaction conditions has not been achieved. Previous works are mostly focused on the single gas conditions, which is apparently not the case in the real catalytic reactions. In this work, a multiscale structure reconstruction model is established to describe the equilibrium structures of metal NPs in a mixed gas environment quantitatively. Taking NO and CO reaction as a model system, the structures of the Pd, Pt, and Rh NPs in a large range of temperature and pressure are fully presented. Moreover, we show the variation of P-NO:P-CO Plays the critical role in determining the structures and therefore the number of active sites of the NPs at certain conditions. This work provides an efficient model to guide the future experiments in the real reactions.
